Valve is releasing a new shooter via Steam free of charge, with top-down four player co-op shooter Alien Swarm hitting PCs today.

Originally an Unreal Tournament mod, Alien Swarm has been re-imagined in the latest iteration of Valve's Source engine, introducing a string of additions to the 2004 original including Steamworks integration.

The release will also include the full SDK code, should you wish to have a poke around under the hood.

It's being developed by Black Cat, the mod team who created the original and went on to be acquired by Valve in 2008. We'll hopefully be bringing you fuller impression of the game in the near future.
